android - java.lang.IllegalArgumentException：服务未注册：ls@1ff721a

Question

我正在使用firebase_messaging 7.0.3和flutter_local_notifications 4.0.0在 android 中发送通知，一切正常，我还使用 SQLite 保存通知，它仍然可以正常工作，除非后台模式我可以看到通知，但看起来像函数我为保存未调用的通知而创建的。

代码句柄通知

    _firebaseMessaging.configure(
  onBackgroundMessage: Platform.isIOS ? null : myBackgroundMessageHandler,
  onMessage: (Map<String, dynamic> message) async {
    MessageNotification notification = MessageNotification(
        id: null,
        title: message['notification']['title'],
        body: message['notification']['body'],
        status: 'U',
        createdDate: formatted);
    await dbHelper.save(notification);

    showNotification(
        message['notification']['title'], message['notification']['body']);
    messages = await dbHelper.getMessages();
    if (messages.isEmpty) {
      messages = [];
    }
    update();

    print("onLaunch: $message");
  },
  onLaunch: (Map<String, dynamic> message) async {
    print("onLaunch: $message");
    showNotification(
        message['notification']['title'], message['notification']['body']);
  },
  onResume: (Map<String, dynamic> message) async {
    print("onResume: $message");
    showNotification(
        message['notification']['title'], message['notification']['body']);
    messages = await dbHelper.getMessages();
    update();
  },
);

}

代码句柄后台保存

Database db;
const String ID = 'id';
const String TITLE = 'title';
const String BODY = 'body';
const String STATUS = 'status';
const String CREATEDDATE = 'createdDate';
const String TABLE = 'Message';
const String DB_NAME = 'message2.db';
Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
  print('on background running');
  MessageNotification notification = MessageNotification(
      id: null,
      title: "Hello",
      body: "hello",
      status: 'U',
      createdDate: "2020-10-2020");

  await db.insert(TABLE, notification.toMap());


  return Future<void>.value();

  // Or do other work.
}

应用程序.java

public class Application extends FlutterApplication implements PluginRegistrantCallback {
@Override
public void onCreate() {
    super.onCreate();
    FlutterFirebaseMessagingService.setPluginRegistrant(this);
}

@Override
public void registerWith(PluginRegistry registry) {
    FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
    FlutterLocalNotificationsPlugin.registerWith(registry.registrarFor("com.dexterous.flutterlocalnotifications.FlutterLocalNotificationsPlugin"));
    PathProviderPlugin.registerWith(registry.registrarFor("io.flutter.plugins.pathprovider.PathProviderPlugin"));
    SqflitePlugin.registerWith(registry.registrarFor("com.tekartik.sqflite.SqflitePlugin"));
}

}
